PTMP235DCKT Temperature Sensor Equivalent & Substitute Parts

Part Overview

The PTMP235DCKT is an analog temperature sensor manufactured by Texas Instruments, designed for local temperature measurement across a range of -40°C to 150°C. This component operates with a supply voltage of 2.3V to 5.5V and provides analog voltage output at 10mV/°C resolution. The device is packaged in a 5-TSSOP (SC-70-5, SOT-353) surface mount configuration.

The PTMP235DCKT is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this temperature sensing solution.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PTMP235DCKT is determined by the following critical parameters:

• Sensor type classification (Analog, Local)
• Local sensing temperature range (-40°C ~ 150°C)
• Analog voltage output configuration
• Supply voltage compatibility (2.3V ~ 5.5V)
• Output resolution (10mV/°C)
• Operating temperature range (-50°C ~ 150°C)
• Surface mount packaging in 5-TSSOP / SC-70-5 / SOT-353 form factor
• RoHS3 compliance and MSL rating

The TMP235A2DCKT meets all specified parameters and qualifies as a direct substitute for the PTMP235DCKT.

Parameter Comparison

Engineering Selection Recommendations

Both the PTMP235DCKT and TMP235A2DCKT are classified as obsolete products. The TMP235A2DCKT is the designated substitute for the PTMP235DCKT and maintains full electrical and mechanical compatibility across all specified parameters.

Selection between these parts should be based on:

• Availability and inventory status: TMP235A2DCKT currently has significantly higher inventory availability (31,982 pcs) compared to PTMP235DCKT (687 pcs)
• Packaging format: Both parts are supplied in identical 5-TSSOP SC-70-5 surface mount packages
• Regulatory compliance: Both parts maintain ROHS3 compliance, REACH unaffected status, and identical EAR99 export classification
• Moisture handling: Both parts carry MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints

The TMP235A2DCKT is available in Cut Tape (CT) and Digi-Reel® packaging formats, providing flexibility for different procurement and assembly workflows.

Frequently Asked Questions (FAQ)

Q: Can the TMP235A2DCKT be used as a direct replacement for the PTMP235DCKT in existing designs?

A: Yes. The TMP235A2DCKT is electrically and mechanically equivalent to the PTMP235DCKT. Both devices share identical sensor type, temperature range, output characteristics, supply voltage requirements, resolution, operating temperature range, and package configuration. No circuit modifications are required.

Q: Are there differences in accuracy specifications between these parts?

A: The TMP235A2DCKT specifies an accuracy rating of ±0.5°C within the 0°C ~ 70°C test condition range. The PTMP235DCKT does not provide a specified accuracy value in the available documentation. Both parts operate across the same -40°C ~ 150°C sensing range.

Q: What is the significance of the packaging format difference (Cut Tape vs. standard packaging)?

A: The TMP235A2DCKT is available in Cut Tape (CT) and Digi-Reel® formats, which are standard distribution methods for surface mount components. These formats do not affect the electrical or mechanical properties of the component itself. Selection depends on assembly process requirements and procurement preferences.

Q: Are both parts RoHS compliant?

A: Yes. Both the PTMP235DCKT and TMP235A2DCKT are ROHS3 compliant and carry REACH unaffected status, meeting current environmental and regulatory requirements.

Q: What is the moisture sensitivity level for these components?

A: Both parts carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints. Standard handling and storage procedures are sufficient; no special moisture control measures are required.
